I have some 215's sitting in the garage. Would you take the 370's out and put the them in and then maybe but some 191's in? I like the 370's but I hear lots of bad things about them. I also have a edge jammer bb/turbonetics stage 1 that I got for a hell of a deal that i just put on?

 

sell your 370's and 215's get some new era 370's and hopefully have some change left over.

or deal with the smoke from marine 370's

my 191's added alot of low end smoke

 

Your experience with the 370's should dictate whether you want to ditch them. You won't have the same power with 215's and 191's as you will with 370's and 181's.

If you just put on that Edge turbo, run it and decide for yourself whether you want to keep it or not. If you like them, why get rid of it?
